Rubber-plastic material uses high-quality rubber and polyvinyl chloride (NBR / PVC) as the main materials, and is a mixed foam material formed by mixing, mixing, continuous extrusion, heating foaming, cooling and cutting. In the process of mixing rubber and plastic insulation materials, in addition to the mixed rubber materials, some other mixing auxiliary materials usually need to be included. The mixing auxiliary materials are usually in powder form. The powdered mixing auxiliary materials have agglomeration. The agglomerated mixing auxiliary materials may cause melting and agglomeration during the mixing process, which is difficult to separate, resulting in defects in the produced insulation materials and reducing product quality. When screening the mixing auxiliary materials, the mixing auxiliary materials are easily accumulated on the feed screen plate and the feed filter plate, which reduces the screening speed and may even cause blockage, reducing work efficiency; after screening the mixing auxiliary materials, the agglomerated mixing auxiliary materials accumulate in the feed screen bucket and need to be manually processed and cleaned, which has low work efficiency and is not conducive to the promotion of equipment.

[0031] See also Figure 1-Figure 10 A feed hopper 101 is provided on the side of the feed screen hopper 201, and the feed hopper 101 is fixedly connected to the mixer 1; When in use, the main material to be mixed enters the mixer 1 from the feed hopper 101 .

[0032] A mixing method for processing thermal insulation materials, using the above-mentioned proportioning mixing equipment, comprises the following steps: The mixed powdered auxiliary materials are introduced into the feed screen 201, and the feed screen 201 screens the mixed auxiliary materials. The screened mixed auxiliary materials fall down and enter the mixer 1 through the feed filter plate 203 for mixing; During the process of feeding and screening the mixing auxiliary materials, the feeding moving rod 205 moves back and forth, thereby driving the feeding knocking block 204 to move back and forth. The feeding knocking block 204 moves back and forth up and down during the horizontal movement, and knocks the bottom surface of the feeding screen plate 202 and the top surface of the feeding filter plate 203, so as to prevent the mixing auxiliary materials from accumulating on the feeding screen plate 202 and the feeding filter plate 203, thereby speeding up the screening process; After the screening is completed, the cleaning grinding plate 301 moves to the top of the feed screen plate 202 and gradually approaches the feed screen plate 202. The feed screen plate 202 moves back and forth horizontally in a small range during the movement to grind the mixing auxiliary materials agglomerated on the top surface of the feed screen plate 202. After the grinding is completed, the cleaning grinding plate 301 moves upward for a distance, and the cleaning roller 302 moves and rolls along the top surface of the feed screen plate 202. The rubber rod 303 enters the sieve holes of the feed screen plate 202 during the rolling process, and pushes out the mixing auxiliary materials in the sieve holes of the feed screen plate 202, so that they fall onto the feed filter plate 203. The feed knocking block 204 moves back and forth to knock the bottom surface of the feed screen plate 202 and the top surface of the feed filter plate 203, so that the ground mixing auxiliary materials enter the mixer 1.
